IMPROVBD BRICK MACHINE.

TO ALL WHOM IT MAY CONOERN:

Be itknown'that I., PHILIP H. KELLS, of Adrian, in the county ofLenawee, and State of Michigan, have invented certain new and usefulimprovementsin Brick Machines; and I do hereby declare the following tohe a. full, clear, and 4exact description of the same,'reference beinghad to the accompanyingdrawings, which are made part ofthisspecification, and in which- Figure lis a sectional elevation of a brickmachine embodying my invention, the plane of vertical section .beingindicated by the linesziz, fig. 2.

Figure 2 is a top view ofthe same partly in section, the planes ofhorizontalsection being indicated by the lines y y, fig. 1. i v l Figure3 represents a vertical sectionon the line z z, tig. 2. Y

Similar letters of reference indicate corresponding parts in the twofigures.

This invention relates to certain improvements in the brick machine forwhich Letters Patent, numbered 63,057, werevgranted tome on thenineteenth day of March, 1867.'

One feature of the present improvement consists in the method ofconstructing the bed-platc for the reception ofthe pug-mills, said platebeing of a single piece of metal, which is cast solidly with annularlanges, into k which-the lower ends of the cylinders or pug-mills areinserted.

The invention also consists in the arrangement of a stationary plate,which sustains the pressure when the followers are madctc act upontheclay, and which is formed with a sharp cuttingedge, which occupiesaposition on the interior of the pug-mill at the point where theiilledmoulds pass fromvbeneath the discharge aperture in the bottom of thesaid pug-mill, and which serve to shave or remove the superfluous clayfrom. the mouldsr Vand .leave the same inside ofthe clay-mili or tub.

.The invention-also consists in adjust-.ably supporting the bed-plate,so that from time to time, to compensate for wear on the fctionaiAsurface of the mould-wheel and bedplate, it may be moved and set or heldin`closer proximity tothe latter' in order to prevent the clay fromworking out between the joints.

.The invention furtherrconsist-s ina lnovelfmethod 'of arranging andadjusting-the inclins which elevate the followers to compress the `clayin `-the moulds; -constructing and applying a smoothingfknife andclay-guard;

.adjusting the rollers upon whichthe mould-wheel revolves, and arrangingthe 'gearing by which the mouldwheel is driven, all as will behereinafter ful-ly explained. p I i In the accompanying drawings, A mayrepresent a suitable base or frame, upon which the several operatingparts of the machine are mounted. B is a bed-plate, supported upon thepillars or posts C C, the upper ends of which areprovided withscrew-threads and tted to the threaded sockets D D. By the rotation ofthe posts C the bed-.plate B may be lowered so as to bring it snuglyagainst thel surface of the mould-wheel E, and thus prevent the clayfrom working out between the joints. j ".lhis adjustment is made fromtime to time in order to compensate for the wear to which the frictioualsurfaces of the bedplate andmould-wheel are subjected. .The adjustmentof the hed-plate may be effected by any othersuitable means. Thebed-plate B is cast in one piece and is formedsol'idly, and, inconjunction with the annular ilanges B1 B1, which receive the lower endsof thel pug-mills F F, and confine them in position upon the bed-plateB. Stay-rods F1 F1 and nuts are employed to hold the pug-millslrmly inposition.V G is a horizontal driving-shaft, which may be driven bya'hand upon the pulley Ghaud which communicates motion to the pug-millshafts F2 F2 through the gearing GrzG G3 G3. The clay'is agitated andworked to the proper consistency by the arms or blades Fa on the rotaryshafts Fil F2, and is ejected through the discharge aperture Hl at thebottom of each pug-mill .F by the spiral wings F4. I I are verticalshafts, rising fromeither end of the hed-plate'B, and rotated by theshaft Gr through'suitable gearing G5 G6. The lower ends of the shafts II carry gear-wheels l1 Il, which communicate a rotary motion to themould-wheel E `through the intermediate gear-wheels `Iz I2, which meshywith the cogs ou the periphery of mouldwheel E. The frame lin which thedriving-shafts have their bearings is erected upon the bed-plate B, andmoves with the latter under the adjustment to which it is subject.J-{see fig. 3) represents a plate, which issecure'd to the under side ofthe bed-plate B in proximity to the aperture Hl, through which the clayis forced from each of the pug-mills F into the'mo'ulds e of themouldwheel E. Each of these platesJ is formed with a sharp cutting edge,which rests upon the face of thcmould=wheel E, and serves to shave offandwremovei'the superiluous clay from the top of moulds e, as thelatter-pass from beneath the aperture H1; most of the superiiuous clayis thus prevented from passing ont of the pug-mills. As soon as a filledmould, e, reaches a point immediately' beneath the plate J, the followerK of that mould is forced upward by the Contact of its roller K1 withthe incline' L, the clay being thereby firmly compressed between lthefollower K and plate J. The bar of metal upon which the incline L is'formed is adjustable vertically by meansof the rods M and nuts m, forthe purpose of' adapting the machine to be set from time to time tocompensate for the wear which is duo to friction.- It willalso be seenthat while the clay is being subjected to the action of the follower K,the rods M serve to hold that part ofthe bed-plate, and thus relieve thesupporting frame of undue strain. A knife, N, employed in connectionwith eachpug-mill to removerany superfluous clay which may project abovethe moulds e, when the llatter have passed from under the bed-plate. AsJghe filled moulds'emeige from under the bed-plate and pass beneath theknife N, the latter removes whatever superfluous clay there may be atthe top of-the moulds, and the clay thus removed is prevented fromgetting upon that part of the wheel E containing the preceding moulds bythe shield-N1, which is a flat piece, secured edgewise to the knife N bymeans of the threaded rod 71, and nut4 nl at its outer end, and by theprojection [12 on the bed-plate at its inner end. The outer end of theknife N is held against horizontal displacement by means of the rod n,while the inner end of the knife abuts against the stud it?, whichserves to `properly retain the knife in position wit-hout fastening orattaching it to thev bed-plate. The set-screw n3, together 'with the nutnl, serves to hold the knife N snugly in contact with the face of themould-wheel E. Both of the longitudinal edges of the'knfe N are groundto an edge, so thatgwhen one side becomes impaired by use,` a newcutting edge may be brought into requisition by simply turning thelznifeover. As the mould-wheel continues to revolve, the moulds e aresuccessively carried under the knives N, as above described, and thenthe rollers K1 move in contact with the stationary inclined planes O,and they bricks are ejected upward from theinoulds. v i

The central support of the mould-wheel E may be similar to that shown inmy patent previously alluded to; but in the present case it isrepresented as having two central bearings, e2 e3, instead of O re'asproposed in the previous patent. The wheels l), which afford bearingpoints for the wheel E near its outer rim or circumference, are eachjournalled in a metallieframe, P1, which is fulcrumed oradjustablysupportcd upon the stationary bnse-platePg, lwhich is formedwith `vertical projections pp, for the lateral support of the frame P1,as clearly represented in iig. 2. The arm or limb p1 ofthe frame P-, isheld by a screw-bolt, p2, and nut p3, by turning which latter the frameP1 may be vibrated after the manner of a lever, so as to force thewheels upward and hold them in proper position to aiord the requisitebearing for the wheel E. The tendency ci' the pugfmill 4shafts, when inoperation, is iso force upward the horizontal girt R, which connects theendsof the shaftspporting frames. I therefore propose to employ astay-rod, Q, which, at its lower end, is tapped inte the hub B* on thebed-plate 13 or otherwise fastened thereto, and fastened at the upperside of said girt Rby means 0f nut B5.

i Having thus described my invention, the following is what I claim asnew herein, and des-ire to secure by Letters Patent: I

1. Iclaim the bed-plate B, formed with the annular anges B1 B1, for thereception of the pug-mills F F, substantially as described.
